The post-earnings rally in mega-cap tech has turned into a genuine squeeze, it seems. Microsoft (NASDAQ:MSFT | MSFT Price Prediction) stock is up 27% over the past month, and Microsoft shares are up 2% to $497 Tuesday afternoon. Meanwhile, Amazon (NASDAQ:AMZN) stock is up 14% over the past month; it’s also down 2% to $277 today, but that could just be a speed bump
Both Microsoft and Amazon ranked among the most heavily shorted mega-caps heading into their late-July earnings reports, based on our prior reporting. The setup left short sellers exposed to any upside surprise, and both companies delivered decisive beats. The result has been a forced-covering scramble that has powered the group across every session since the prints
The Invesco QQQ Trust (NASDAQ:QQQ) has ridden the move higher. The NASDAQ 100 tracker holds Microsoft, Amazon, and Meta Platforms (NASDAQ:META) among its top positions, giving investors a broad, non-leveraged way to play the group. Its concentration in mega-cap technology remains heavy, so single-name earnings continue to steer the fund
Short Squeeze Meets AI Capex Confidence
Ahead of the reports, short positioning in Microsoft and Amazon had built to levels our prior coverage flagged as historically stretched for mega-cap tech. Cloud growth reaccelerated at both companies, Wall Street’s tone turned more positive after the beats, and the combination pulled shorts off their positions in a hurry. That mechanical bid is a big reason the moves have looked outsized relative to fundamentals alone
The rally reflects more than mechanics, however. Prediction markets on Polymarket now assign a 93.5% probability that Amazon’s 2026 capital expenditures exceed $200 billion, signaling that traders read the move as validation of AI infrastructure demand, not just a fleeting cover-driven pop. Amazon’s crowd has been correct on 74.1% of resolved markets, which lends weight to the positioning
Microsoft’s post-earnings composite sentiment score sits at 74.43, a bullish reading with medium confidence. The Microsoft earnings-day move stands out against a six-quarter average day-of change of 2%, underscoring how forcefully the squeeze cleared the deck
Lately, Retail chatter has swung with the price action. WallStreetBets sentiment on Microsoft stock reached 94 in the days after earnings, a very bullish reading, and threads covering Amazon stock maintained bullish scores in the 62 to 77 range through the past week. Retail engagement at that intensity often accompanies short-covering rather than initiating it
Meta Platforms Sits Out the Rally
Meta Platforms was the third heavily shorted name in our prior coverage, but META stock hasn’t joined the squeeze. Meta Platforms stock is down 11% year to date and is little changed near $587.64 on Tuesday
Meta Platforms reported a mixed quarter, with a bottom-line miss snapping a six-consecutive-quarter streak of beating expectations. That gave short sellers less reason to cover, and Polymarket contracts still lean bearish on Meta Platforms stock for Tuesday’s session with a 70% down probability. Reddit chatter on Meta Platforms has drifted back toward neutral even as Microsoft and Amazon threads stayed bullish through the past week
What Investors Can Watch Now
Investors can watch for whether Microsoft and Amazon shares hold their post-earnings gains as August progresses. Prediction market participants are already flagging near-term consolidation risk on Amazon, and Microsoft’s own month-end market is only assigning a 36.5% probability of a close above $510 by August 31. That’s a meaningful signal after the run
The valuations across the group sit at elevated levels, and short squeezes can reverse quickly once forced buyers finish covering. Traders should size their positions to reflect that the easiest part of the move may already be behind Microsoft and Amazon shares, even if the AI capex thesis continues to support the longer fundamental case
Meta Platforms’ underperformance suggests that shorted-name rallies are selective. The bid is chasing companies with clear cloud and AI monetization stories, not the entire cohort of pre-earnings short targets. Keep an eye on Microsoft and Amazon shares into the end of the week to see whether momentum holds or the tape begins fading the squeeze
